5-Nitro-2-furylcarbamoyl derivatives were found to form a colored complex by the action of a strong base. It was assumed from the ultraviolet, infrared, and nuclear magnetic resonance spectra of these colored complexes that the N-proton of the corresponding carbamoyl group is extracted by the action of a strong base and the molecule as a whole becomes an anion to form the complex.
